% [03/01/200* 10:55:38-] FC-5-070c1004: The origin of fib(192.168.0.2) is wrong

Handling Process

1. Change address of static user as 192.168.0.222 and it is normal. User's PC and data configuration of MA5200F can be ironed out.2. According to the alarm check FIB of the equipment, find:192.168.0.2/32 218.206.*.* GHU t[0] Ethernet1.0The static user is configured at port 7 and the next hop of FIB is port 1.3. Check route table of the equipment, find:192.168.0.2/32 O_ASE 150 1 218.206.*.* Ethernet1.0 From connection equipment of port 1, find accurate route of released 192.168.0.2. The upper equipment route releases the same host route as IP of static user, so user cannot communicate. Change released route of upper equipment and it is no problematic.

Root Cause

Opposite equipment releases host route the same as static route address. MA5200F finds the route through OSPF and adds it in corresponding FIB. When configured static user is online, the flooding of corresponding FIB fails because the destination address is the same as that flooded by route protocol. So the forwarding packet of static user fails and user cannot access network normally.

Suggestions

Only released route is accurate host route, the problem occurs. Notice the planning of IP address of the network during configuration. Do not introduce and release wrong route information.
